Ceramic Matrix Composites : Lifetime and Strength Prediction Under Static and Stochastic Loading

Ceramic Matrix Composites: Lifetime and Strength Prediction Under Static and Stochastic Loading focuses on the strain response and lifetime prediction of fiber-reinforced ceramic-matrix composites under stress-rupture loading at intermediate temperatures. Typical damage mechanisms of matrix cracking, interface debonding and oxidation, and fiber’s oxidation and fracture are considered in the micromechanical analysis. Effects of composite’s constituent properties, peak stress, and testing temperature on the composite’s strain response and lifetime are also analyzed in detail.

Finally, a comparison of constant and different stochastic stress spectrum on composite’s damage evolution and fracture is discussed. This book will be a practical guide for the material researcher and component designer needing to better understand the composite’s damage and fracture behavior under stress-rupture loading at intermediate temperatures.

• Contains detailed analysis of the stress-rupture behavior of fiber-reinforced ceramic-matrix composites
• Includes experimental data on stress-rupture behavior of different CMCs
• Presents micromechanical constituent models for characterizing damage and fracture behavior under stress-rupture loading
• Provides data on the physical properties of each constituent at various temperatures, along with the composite’s response
